Abstract

La présente invention concerne un réseau de diffraction (10') servant au multiplexage et démultiplexage de signaux optiques dans des systèmes de communication optique dont la sensibilité à la polarisation a été atténuée. Ce réseau comporte une pluralité de surfaces réfléchissantes en gradins (16') séparées par une pluralité de surfaces remontantes (18') définissant les rainures du réseau. Ces surfaces en gradins (16') sont rendues réfléchissantes par un revêtement (22'), les surfaces remontantes (18') ne comportant par de revêtement conducteur. L'invention concerne également un procédé de réalisation d'un réseau de diffraction réfléchissant. A cet effet, on commence par former dans un substrat une pluralité de rainures présentant, d'une part une surface réfléchissante permettant de renvoyer un faisceau incident, et d'autre part une surface non réfléchissante. On applique ensuite sur la surface réfléchissante un revêtement réfléchissant, mais non pas sur la surface non réfléchissante.
